TOBACCO PIPE.

. Application filed May 20,

T 0 all whom it may concern:

Be it known that L JoHN D. MAIER, a citizen of theUnited States.residing at Charlestown, in the county of Cecil and State] of Maryland,have invented new and useful Improvements in Tobacco Pipes, of which thefollowing is a specification. The object of my present invention is theprovision of a tobacco pipe constructed with a view to affording a coolsmoke and to be expeditiously and thoroughly cleaned when occasiondemands without the assistance of extraneous means other than a wad ofsoft paper or other appropriate soft material.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a longitudinal vertical central section illustrative of my noveltobacco pipe.

Figure 2 "is a view partly in elevation and partly in section showingthe ferrule and the tube "associated therewith.

Figure 3' is an enlarged transverse section taken in the plane indicatedby the line 3--3 of Figure 1.

Figure 4 is a side elevation of the removable element of theimprovement.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

In accordance with my invention the pipe bowl 1 and its stem 2 areformed in one piece, and in the stem 2 is provided a bore 3 of largediameter throughout its length and extending from .the bottom portion ofthe bowl rearwardly as illustrated. Permanently arranged on the rearreduced portion 4 of the stem 2 is a metallic ferrule 5, andappropriately fixed in the said ferrule 5 is the rear comparativelylarge poi'tion 6 of a metallic tube 7 which is designed to tightly fitin the stembore 3 and to remain permanently therein. For the sake oflightness the ferrule 5 and the tube are preferably of aluminum. Snuglyfitting in the portion 6 of the tube 7 is the reduced forward portionofa removable mouth piece 8 which may be of any material compatible withthe purpose of my invention, and arranged removably in the tube 7 is thesmoke cooling and cleaning element of the improvement; the said elementbeing numbered 9' and being pro-' 1921. Serial No. 471,051.

piece-8 so that when the said mouth piece 5. y

is removed theelement 9 will also be re moved. In addition to the stem10 the elc ment 9 includes a shank 12 integral with and extendingforwardly from the enlargement 13 at the forward end of the stem 10, anda spiral fin 14 which is designed to snugly fit in .the tube 7 and forma tortuous smoke passage with a view to cooling the smoke before itreaches the mouth of the smoker- At its forward end the shank 12 isprovided with a hook 15 which hook extends about the proportionaldistance illustrated forwardly of the forward end of the fin 14 for apurpose hereinafter set forth. For the sake of lightness the element 9is also preferably formed of aluminum, but it will be understood fromthe foregoing that the material 'or materials of which the ferrule 5.tube 7 and removable element 9 are formed are not of the essence of myinvention.

When the novel pipe is to be used the parts are arranged as illustratedin Figure 1, and consequently it will be understood that in passingthrough the tube 7 the smoke will be caused by the spiral .Vfin l ltofollow a tortuous course en route to the s'mokers mouth so that when thesmokereaches the mouth it will have been materially cooled.-

other sediment out of the tube 7. Then -1 and the hook end 15 isutilized as a pick to engage the wad or swab and withdraw the same fromthe bowl. Manifestly in this I way the pipe may be expeditiously andthor oughly cleaned, and then when the element 9 v and the mouth piece 8are properly positioned relatively to the tube 7 from the rear. the pipewill be restored to condition for use.

It Will also be manifest "from the toregoing that so far as outwardappearance is concerned my novel pipe presents the usual neat appearanceof an ordinary pipe.

It will further be ap n'eeiated from the foregoing that my improvementissimple and inexpensive in construction and is adapted*to materiallyprolong the usefulness of the pipe as a Whole.

Having described my invention, what 1 claim and desire to secure byLetters Patent, is

In a tobacco pipe a bowl and a. stem ex-.

tending from the bowl and having a bore in communication With theinterior of the bowl l5 and also having an exteriorly reduced rear end,a ferrule permanently fixed on said reduced end of the stem, a tubehaving a rear enlarged portion permanently secured in the ferrule, saidtube rest-111g snugly 1n the stem 20 aneans removably arranged in thetube and removable from the pipe with the mouth 25 piece.

In testimony whereof I afiix my signature.

JOHN D. MAIER.
